  • Tailing Disposal Methods and Tailings Dam Construction Design

    Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the damTerminology Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terracone (terrikon) Examples Sulfide minerals The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry" These tailings contain large amounts of pyrite (FeS 2) and Iron(II) sulfide (FeSTailings Wikipedia

  • Retreatment of gold residues ScienceDirect

    Jan 01, 2005· Goldmining residues typically fall into one of three categories comprising slime (particle size of about 75% passing 74 μm), sand (about 10–20% passing 74 μm) and waste rock Since the slime and sand has been previously processed, it typically has a low gold grade (<10 g/t) and will provide relatively low recovery efficiencies, in thedisposed onto slimes dams by gold mining activities in South Africa (Winde and De Villiers, 2002a;b; Winde 2003) In addition to this most gold tailings produced before 1952 were never leached for U (a few old slimes dams, however, were later reworked to recover U), and therefore also contain U in elevated concentrations as found in the mined oreGold tailings as a source of waterborne uranium
